9 Claims. (Cl. 242118.8)

The present invention relates to a wire dispenser and in particular to a roll-type dispenser and to a means for making the same.

The conventional wire dispenser now commercially used is conventionally made of metal or similar permanent material and is provided with a cylindrical core with two flanges positioned at the ends of the core and normal to it, the flanges being integrally secured to the core. This conventional type of wire dispenser is relatively expensive in view of the cost of the material and labor involved in its manufacture. Consequently, most dispensers of this type are re-used many times and give rise to cumbersome accounting systems involving both the wire manufacturers and their purchasers. It is an object of the present invention to provide a commercially acceptable throw-away dispenser made of inexpensive materials and by a simplified method of manufacture. In this connection, the present invention provides a rolltype dispenser of fiberboard, craftboard or similar material with the various components being cemented together into an integral unit.

The present invention also provides a method for assembling the components of the dispenser in a manner which is more efficient and rapid and less expensive than those previously known. The method practised further utilizes substantially all of 'the component parts of the dispenser without any portions of the die-cut elements being discarded as waste material. These and other objects and advantages of the present invention will be more clearly understood whenconsidered in connection with the accompanying drawings, in which:

Figure 1 is a cross-sectional elevation of a cylindrical roll taken substantially through a diameter of the roll, and Figure 2 illustrates the embodiment of the invention shown in Figure l as viewed from the left side.

In the structure illustrated, the component parts of the invention may be made of any inexpensive material such as fiberboard, craftboard, cardboard or other similar material, provided the material is relatively stifi. Two end plates 1 and 2 and a center core or cylinder 3 form the essential and basic components of the dispenser structure. The end plates 1 and 2 are illustrated as being round. However, other suitable shapes may be used for these members, as well as for the cylinder 3, if desired. The end plates 1 and 2 each have a central portion or cover element 4 die cut from the remaining portions of the plates whereby the central portions 4 may be displaced from the plane in which the remaining or annular portions of the plates 1 and 2 are located. The periphery of the central portions 4 conform to the outer surface of the core 3 both as to size and shape. The center core 3 has its ends fitting into the openings in the plates 1 and 2 created by the displacement of the central portions 4. The ends of the core 3 project only substantially halfway through the thicknesses of the plates 1 and 2 and abut at their ends the inner peripheral surface of the central portions 4 which project beyond the outer surfaces of the plates 1 and 2. The core 3 is cemented to the plates 1 and 2 at 5 and 6. The portions 4 are secured to the ends of the core 3 by cement located at points 8. This securing of the core and plates together as indicated may be accomplished by use of any suitable cementing means which will securely and rigidly hold the various components of the roll or spool together. Some cement should also be positioned between the adjacent sides of the central portions 4 and plates 1 and 2.

The central portions 4 are provided with die-cut openings 9 and 10. Openings 9 are adapted to support the dispenser on a spindle for rotation in dispensing the roll from the reel, while the openings 10 are provided to receive a shaft or pin for causing the unit to turn at a desired speed.

In forming these wire dispensers, two end plates 1 and 2 are die cut to any suitable and desirable shape, such as a disc as illustrated. Preferably simultaneously, the central portions of these end plates 1 and 2 are also die cut so as to be adapted to be punched out or displaced from the center of the main body of the end plates 1 and 2. At this initial stage, however, these central portions 4 are allowed to remain in the plane as their respective end plates 1 and 2. j A core 3 of suitable length and having the same size and shape circumference as the central portions 4 is selected. A quantity of cement may then be placed about the die-cut opening forming the central portions 4 with the cement extending preferably inwardly from the die cut a marginal width equal to the thickness of the wall section forming the core 3.

Preferably, however, cement is deposited on the end sur-.

faces of the core 3. The core 3 is then positioned in direct alignment with the portion 4 and is uniformly moved towards it. The core 3 is then uniformly pressed partially through the end plates 1 and 2 at each end displacing from the plane of their respective plates the central portions 4. The core 3 should be forced through the tight-fitting end plates 1 and 2 to a point at which the portions 4 are displaced partially out of the plane in which they were formerly located. In this position, some cement will seep between the adjacent edges of the central portions and the plates 1 and 2. To accomplish this, suitable supports should be utilized which permit the displacement of the central portions 4 a selected distance from the plane in which the end plates 1 and 2 are located. This displacement will cause the cement to spread about the ends of the core 3 and the inner surfaces of the end plates 1 and 2 at points 5, 6 and 8. For this purpose, a relatively quick-drying cement should be utilized so that the end plates 1 and 2 will be rigidly secured in position once they are disposed about the core 3. In carrying out the method above suggested, the openings 10 in each center section 4 should be aligned one with the other for purposes of uniformity in structure.

This over-all method of producing the dispenser will provide a structure of substantial rigidity from inexpensive material with the process being adapted to be readily mechanised. Subsequent to this operation, a selected quantity of wire 11 may then be coiled in a conventional means about the dispenser.

It may be noted in connection with the cementing of the end plates to the core that the out between the plates and central portion formed by the die is sufiicient to permit the seepage of the cement between the plates 1 and 2 and the central portions as indicated above. The preferable way of applying cement is to apply it to the ends of the tubes so that the excess cement in addition to seeping down between the central portions and the plates as indicated above will also be positioned between the ends of the core and the inner surface of the central portions 4, thus providing further and substantial securing strength to the entire structure. The strength which is obtained by cementing the roll dispenser in this manner is sufiicient to avoid warping or bending of the plates with respect to the core or cylinder 3. -I1rwi1rding the wire ontodispensers-of the type set forthzabove no arbor or adaptor is necessary to strengthen the end plates andthereby avoid'warping or bending during the winding process as is common on dispensers of other types. Asubstantialportion of the strength imparted to the assembly as described above is obtained through the provision of a substantially greater area of cementingsurface than has previously been obtainable in the structures heretofore known.
